Made this tonight for the family. Everyone said it was great! The only changes I made were using canned sliced mushrooms to save on cost (fresh would have been better) and frozen chicken breasts that were thawing all day in the marinade. They weren't 100% thawed, so the chicken spent some extra time in the skillet, and then I popped it in the oven for 9 minutes without topping to finish it off cooking. Didn't have parsley on hand. Yes, it definitely tasted like the original and as our eating-out budget doesn't really include Outback anymore, this was wonderful!!
Very easy and turned out great. A little salty, but I put more stuffing mix (and off-brand) under it than it called for, so it probably absorbed some salt from that. I also used more cheese because my family loves cheese. I used frozen breasts and frozen broccoli. I cooked broccoli in the microwave for 4 minutes (steamed) before using and the breasts were in the fridge thawing for about 4 hours before putting this together. Took about 45 minutes in my convection oven to be completely done. Husband said he would use thawed breasts and cut them in half so you could stuff them with the stuffing. Not me - that's too hard ;)
